Vanadium compounds were prescribed as therapeutic agents for anaemia, chlorosis, tuberculosis and diabetes. vanadium was also used as an antiseptic. Clinical feature of poisoning shows a broad spectrum of toxic effects of vanadium on the respiratory, circulatory and central nervous systems, the digestive organs, kidneys, and skin. Toxic and biological effects of vanadium depend not only on the total concentration of vanadium but also on the chemical species of vanadium in a sample. Of the chemical species of vanadium (from -1 to +5), vanadium(Ⅳ) and vanadium(Ⅴ) mainly exist in the environment, and the vanadium(Ⅴ) is more toxic than the vanadium (Ⅳ). Thus, an accurate determination of each species is typically critical to evaluate the environmental and biological risks. In this study, we have focused on speciation method of vanadium species (V4+ and V5+) using ICP-OES coupled with IC (Ion Chromatography). The 2.5 mM EDTA was used for the extraction of vanadium species from various samples.
